Calgary researchers to look at aging brain as study says vitamin D prevents dementia – CTV

March 1, 2023

Researchers at the University of Calgary are starting a national project to try to get more insight into the brain as people age.

The CAN-PROTECT project, led by Dr. Zahinoor Ismail, begins Wednesday – the same day that a new paper he co-authored shows taking vitamin D could help prevent dementia.

“We compared older adults who were on vitamin D to those who were not on vitamin D over 10 years for the rate of development of dementia,” said Ismail, a professor of psychiatry and neurology at the U of C and the University of Exeter in the United Kingdom.

The 12,000 participants in the study, published in the journal Alzheimer’s & Dementia, were part of the National Alzheimer’s Coordinating Center in the United States. They had an average age of 71 and didn’t have dementia when they signed up for it. About 37 per cent of those involved took vitamin D supplements.
